A Will County man was issued a traffic citation following the fatal crash that killed a pregnant mother and her three sons last week, but prosecutors dismissed the ticket Tuesday, records and interviews show.

The 25-year-old driver initially was issued a traffic citation accusing him of disregarding a stop sign before the July 24 crash in unincorporated Washington Township. The charge was dropped during a Tuesday court hearing.

Will County State's Attorney James Glasgow on Wednesday said the case remains active and is under investigation. He could not say if further charges would be filed, but noted a resolution on the traffic citation could have posed double jeopardy issues if more serious charges were later filed. Double jeopardy prevents a person from being tried twice for the same or similar offense.

"Obviously, we don't want a plea on that charge and have double jeopardy bar us from any future charges," Glasgow said, adding he was uncertain if other charges would be filed. "This was the right thing to do."

Though the citation has been dropped, it can be re-issued at a later date, Glasgow said. No criminal charges have been filed in the case.

The Will County man initially was scheduled to appear in court on August 24 for the traffic citation. His defense attorney George Lenard, however, requested an earlier date noting a scheduling conflict.

Lenard could not be reached for comment Wednesday.

Beecher residents gathered Wednesday to pay their final respects to Lindsey Schmidt and her three sons.

"This is an indescribable tragedy," Glasgow said.

Schmidt, who was taking her sons to Vacation Bible School, was driving north on Yates Avenue around 8:30 a.m. when she was struck on the driver's side by a truck traveling east on Corning, authorities said. The impact of the crash forced Schmidt's Subaru off the road and into a field on the east side of Yates. The pickup truck landed in a ditch on the north side of Corning, authorities said.

Funeral services take place in Crete on Aug. 2, 2017, for four members of the Schmidt family who were killed in a car crash in Beecher the week before.

Schmidt, who was pregnant, and her toddler son, Kaleb, were pronounced dead immediately after the crash. Her two sons, Owen, 6, and Weston, 4, succumbed to their injuries in the days after the accident. The Will County man, who was driving a 2002 S-10 Chevrolet pickup truck, was treated for an injury to his arm, according to the Will County sheriff's office.

Will County Sheriff's Deputy Chief Tom Budde said the accident remains under investigation pending the outcome of chemical tests and a review of phone records and data from the truck.
